Ds woke cranky and a bit feverish today. Went back to sleep till noon. He has been irritable all day refusing to have any calpol, complaining of feeling cold but refusing a jumper and went to bed at 6.30 (very early for him he usually takes till 9pm to start properly sleeping). I just got in from work and looked in on him and he is flushed with an armpit temp of 38.9. I suspect it's likely a virus as he said he had a sore throat this morning. I'm worried about leaving him but also don't relish waking him, what should I do? Is the temp at a level where I should? Thanks.
